"
Broccoli

Overview

Broccoli contains certain chemicals that may reduce the risk of colorectal or other cancers, although it is not clear which individual compounds may be responsible for the protective effects. While research in this area continues, the best advice at this time to reduce cancer risk is to eat a wide variety of vegetables.

Broccoli is considered a good source of nutrients because it is rich in vitamin C, carotenoids (vitamin A-like substances), fiber, calcium, and folate (see Vitamin A and Beta Carotene, Folic Acid, and Vitamin C).

It is also the source of many phytochemicals (chemicals from plants) that may have anti-cancer properties (see also Phytochemicals). For example, broccoli contains several compounds called isothiocyanates, including sulforaphane and indole-3-carbinol (I3C), which have been touted as possible anti-cancer agents in recent years. Early studies have shown these substances may act as antioxidants and may boost detoxifying enzymes in the body. Some studies have also suggested they may alter body estrogen levels, which might affect breast cancer risk.

The chemical composition of broccoli and other cruciferous vegetables is complex, which makes it hard to determine which compound or combination of compounds may provide protection against cancer. Eating a wide variety of plant-based foods may be the best way to get the necessary components. "

shit yeah, thanks

I need pumpkin, sweet potato, garlic, coconut and almond butter (almonds, I guess)

for the record, this isn't the assigment - I have to know this shit so I can write a 4 pg paper on the chemical interactions going on in my god damn pot of soup

chemical reactions in a pot of soup..??

its all gonna come down to the oils from the foods and the water separating.
and loosing nutrients due to heat

lol

yeah it was just for whatever recipe we happened to make for this potluck type dinner competition

I made pumpkin soup

what do you suppose are the major components of pumpkins, onions, sweet potatoes and garlic

like... dietary fiber?
what is that chemically?

I mean its gonna be what... glucose and some other shit right?

glucose is blood sugar.

fiber is nondigestible by humans.


Quote :
"cellulose, pectin, gums, hemicellulose, and fibers contained in oat and wheat bran), oligosaccharides, lignin, and some resistant starch.

Functional fiber consists of isolated, nondigestible carbohydrates that have beneficial physiological effects in humans. This includes nondigestible plant (for example, resistant starch, pectin, and gums), chitin, chitosan, or commercially produced (for example, resistant starch, polydextrose, inulin, and indigestible dextrins) carbohydrates."

i would wikipedia those ingredients and check out their properties.

http://en.wikipedia.org/wiki/Garlic
scroll down to properties

Quote :
"The phytochemicals responsible for the sharp flavor of garlic are produced when the plant's cells are damaged. When a cell is broken by chopping, chewing, or crushing, enzymes stored in cell vacuoles trigger the breakdown of several sulfur-containing compounds stored in the cell fluids. "


thats probably what you would want to write about garlic.

yeah I knew glucose was sugar

the fiber is cellulose, I think

but I was trying to get a laundry list of the shit that would be the largest part of vegetables

are you looking for what makes the biggest impact?

im sure everyone agrees garlic has that sharp taste...

and onions also.

both of those come from the phytochemicals that were listed in the garlic wiki (the onion would probably be different, but similar).

probably the starch from potato,and fiber from pumpkin.


or do you want some sort of baking soda mixed with vinegar type reaction.
like what makes them fuse together. which sounds hard. cuz i dont know

nah I'm just looking to see if I can know specifically which carbohydrates and which proteins are in pumpkin

then I want to discuss the intermolecular interactions going on between the ingredients... and the chemical reactions

then make a guess as to what reactions determine the taste and texture of the dish

so for pumpkin the largest components seem to be something like:

cellulose, glucose, fructose (maybe?), amylose and amylopectin

in a way.

fructose and glucose make sucrose.


which is in garlic.
